Abstract: 48,151 ABSTRACT OF THE DISCLOSURE          A molded case current limiting circuit breaker includes separable contacts, an operating mechanism releas-able to effect automatic separation of the contacts, and a high speed electromagnetic trip device operable upon over-current conditions to release the operating mechanism and separate the contacts.  The trip device includes a U-shaped pole piece disposed about a conducting path through the circuit breaker and a movable laminated armature mechani-cally coupled to the operating mechanism and magnetically coupled to the pole piece.  The thickness of the armature is substantially greater than the thickness of the pole piece.  During extreme overcurrent conditions electrodyna-mic force is produced upon the armature by magnetic flux in the pole piece.  Upon saturation of the pole piece, force upon the armature  continues to increase with increasing current due to electrodynamic force produced between the armature and the conducting path.

Abstract: ABSTRACT OF THE DISCLOSURE            The invention relates to a monitor system and method for monitoring the occurrence of events in a cyclical process. Whether the successive events occur at their proper positions within the process, position meaning, for example, a physical location and/or a position in time, is accurately monitored, and the process is stopped and a warning issued when an event is missed. Monitoring can be restarted at a point of interruption with resumption of correct checking for successive events. Moreover, if an event is missed, the process and monitoring may be restarted and the missed event selectively automatically deleted from the list of sequential events for which the monitor system looks. The invention is employed, for example, in connection with a conveyor belt system to detect rips in the belt.

Abstract: WAVELESS  WATERBED   ABSTRACT     THis invention relates to waterbed mattresses.  Waterbed have been beset with a major disadvantage in the tendency for wave motion to be created in the mattress.  Wave motion has been reduced in the prior art by the use of baffles, foam toppings, and gels.  However, such solutions involve high cost in manufactuaring and shipping and pose difficulties to consumers who wish to empty, reposition, and refill their waterbeds.  The present invention overcomes these deficiencies of the prior art by providing a waterbed mattress having a slab of open celled foam substantially submerged in, yet partially suspended above the upper surface of, the liquid fill of the mattress.  The waterbed mattress of the present invention retains the positive qualities of bouyant support and comfort of conventional waterbed mattresses, and reduces the undesired wave motion often created within the mattress. other embodiments of the present invention include a waterbed mattress having a large number of open celled foam particles which will be substantially submerged in, yet partially suspended at the upper surface of, the mattress's liquid fill, such particles being either enclosed in a gauze-like sack or unenclosed within the mattress. The present inven-tion may be incorporated in waterbeds or other body supporting furniture such as chairs and couches in which a liquid fill medium is used.

Abstract: ABSTRACT           A coin sorter has the capability to sort an ad-ditional size of coin by means of an exit chute which ex-tends through a side of a coin hopper.  A rotating pickup plate having notches for coins along its periphery rotates in an inclined plane within the hopper.  Coins of certain denominations will fall through a coin opening at the apex of the rotating pickup plate and will fall into coin slots of diminishing width provided in a rotating core.  The coins are held at a level peculiar to their size and are directed to discharge chutes and collection points for each denomi-nation.  Coins of the denomination which is larger than that which can pass through the coin opening are lifted from a notch by a plow positioned in front of the entrance to the exit chute and the coins travel through the chute outwardly of the hopper to a collection point.  A switch actuator arm is positioned in the path of travel of the larger size coins prior to their entry into the exit chute.  The apparatus may be provided as a kit of parts to convert existing sor-ters to handle an additional denomination of coin.

Abstract: An x-ray imaging system for intraoral dental radiography. The imaging process is based on xeroradiographic principles, the surface of a small photoconductive plate being electrically charged. After insertion into a carrier, to form a light-tight cassette, the photoconductive plate is placed in a patient's mouth and x-ray exposed. The cassette, and the resultant electrostatic charge image therein, is inserted into the system processor, the photoconductive plate removed and transported to a developer station wherein the image is developed using liquid toner. The toner image is then dried and transferred from the photoconductive plate by using a transparent adhesive material and fixed to a white plastic substrate, forming an image member wherein the image can be viewed in reflectance or transmittance. The adhesive material and substrate are stored in separate cartridge compartments. After cleaning, the photoconductive plate is available for reuse. The developed xeroradiographic images are exposed and processed sequentially, processing time being approximately 20 seconds, the developed images having the characteristics of edge enhancement and deletion, the xeroradiographic images therefor having advantages over film images.

Abstract: ABSTRACT A method and a device for irradiating a confined volume of matter, normally situated at a depth, with a beam of high  energy charged or neutral particles.  The characteristic feature of the method is that a beam of charged particles coming from a radiation source is scanned electrically in two orthogonal directions.  To obtain a scanned beam of neutral particles, for example photons, a scanned beam of electrons is caused to hit a target which then emits a scanned photon beam predominantly in the direction of the in-coming electrons of neutral particles.  The device according to the invention includes a beam optical system arranged in the path of a beam of charged particles emerging from a radiation source and having two scanning magnets, each of which admits scanning of the particle beam in one of two orthogonal planes, the scanned beam leaving the last scanning magnet from an effective scanning centre.

Abstract: ABSTRACT OF THE DISCLOSURE       The present invention is directed to a trailer hitch for a vehicle.  The trailer hitch is designed to be connected to a vehicle and permits two degrees of freedom for the hitchpoint.  The first degree of freedom is in a lateral direction which permits the hitchpoint to have freedom to move horizontally in a lateral direction.  This degree of freedom is dampened by a viscous damp-ener to improve the lateral stability of a trailer connected to the hitchball.  Further, springs are provided to resist lateral movement and to restore the hitchpoint to its original position during the pulling of a trailer.  In addition, a second degree of freedom is provided which permits rotation of the hitchball about a longitudinal axis.  Permitting the rotation of the hitchball permits the accidental overturning of a towel vehicle without overturning the towing vehicle.

Abstract: 3Q.          EQUALIZER SAMPLE LOADING IN VOICEBAND DATA SET~            Abstract of the Disclosure In a multipoint data communication system using quadrature-amplitude modulation, a master modem (20) and a plurality of tributary modems (lla, llb...lln) are interconnected via respective transmission channels (13a, 13b... 13n, 16).  Adaptive equalizer circuitry (55, 56) in the master modem equalizes the channel from a particular tributary by multiplying samples of signals received from the tributary by an ensemble of tap coefficients associated with the tributary.  The tap coefficient ensembles for each tributary are stored in a memory (91) from which they are retrieved at the start of transmission from that tributary. Timing-acquisition circuitry (29) within the master modem adjusts the phase of the latter's sampling circuitry (23, 27) at the start of transmission from a given tributary so that the received signals are sampled at the correct time points.  In particular, a timing acquisition signal having spectral components only within the non-rolloff region of the equalized baseband-equivalent transfer function is transmitted by the tributary.  The master samples and equalizes the received timing acquisition signal to form a succession of timing acquisition equalizer outputs.  The time by which the operation of the sampling circuitry is to be advanced or retarded is determined as a trigonometric function of two successive ones of the timing acquisition equalizer outputs.  The timing acquisition signal is illustratively a double-dotting pattern having a four~ symbol-interval period.  That period is integrally related tO the carrier frequency.  This allows the samples needed in order to begin forming the timing acquisition equalizer outputs to be generated by replicating the samples taken over only four symbol intervals.

Abstract: Abstract of the Disclosure A mechanism for resonantly driving a moveable cutter blade located at the base of a concave tool is disclosed.  An  angulate beam has first and second legs meeting at a juncture at an included angle of less than 180°.  The beam includes a mounting flange which extends inwardly from the juncture between the legs.  The beam has a resonant frequency, when restrained at the mounting flange, with a node at the juncture and first and second anti-nodes at the ends. One end of the beam receives a vibratory input at or near the resonant frequency so that the second end vibrates about a neutral position.  The mounting flange is attached to the tool so that the angulate beam conforms to the concave shape of the tool.  The neutral position of the second end of the beam is spaced from the back of the cutter blade within striking distance of the blade.  The input vibration at the first end of the beam causes the second end to vibrate about its neutral position and impart forward impulses to the cutter blade to drive the blade intermittently forward.

Abstract: ABSTRACT OF THE DISCLOSURE An electronic organ having an internal system for fault detection.  Information regarding the actuated keys, tab switches, and control switches of the organ is read into a microprocessor which controls tone generators, filters, and the like in response thereto.  Upon actuation of a unique set of input switches, the microprocessor branches into a diagnostic routine.  In the diag-nostic routine, all of the input and output circuits are sequenti-ally tested so that any faults can be isolated.  A lighted display associated with one set of the switches provides visual output as to the progress of the test sequence.  In addition, when a fault is detected, this lighted display provides information regarding the location of the fault.  Through use of this system, a test of an electronic organ can be performed rapidly, and the test protocol can ensure that no switches or output circuits are accidentially omitted.  In addition, because selection among comparable circuits is accomplished internally by the microprocessor, the subject inven-tion permits technician control over aspects of the organ operation which are normally inaccessible to a musician performing on the organ.  The diagnostic sequence automatically resets when the organ is turned off so that even if a performer accidentally entered the diagnostic mode, the organ would readily return to normal operation. The test sequence can be caused to proceed on an automatic or a semi-automatic basis at the option of the test technician.
